I've just manufacturated my first custom board using the DA14585. I'm not sure about how I should burn the flash memory on my custom board(an AT25DN011 SPI memory). I've been going through the reference files and as I could understand, I should use the Smart Snippets toolbox to burn it, either via UART or JTAG. All the pins on my custom board have been designed as the reference papers.
My first though was to simply connect the pins on my DA14580DEVKIT to my custom board RX/TX pins and try to burn it using the Smart Snippets from it, but I'm not sure if that would be correct. Is this the correct way? Or I should use an external UART dispositive in order to do it, following the communication protocol defined on the AN-B-001 Application Note?
Thanks in advance.
